Patented Apr. 12, 1949 CHLORINATOR Norman Mindham Bell, Northampton, and Wilfrid'Charles Childs, Staverton, Daventry, England Application May 9, 1944, Serial No. 534,838 In Great Britain December 20, 1943 6 Claims.

This invention relates to chlorinators, that is to say, to apparatus for delivering small quantitles of a chlorinating solution for mixing with water.

The object of the invention is to provide a simple apparatus which will function over long periods without attention, and will in fact be suitable for more or less continuous duty.

A further object of the invention is to provide an apparatus in which the quantity of the chlorinating solution will be delivered at the correct rate within very fine limits.

A further object of the invention is to provide an apparatus in which the stored volume of solution available for delivery will not affect the pressure head at the point of delivery, so that the rate of delivery will remain constant irrespective of variations in the supply vessel.

A further object is to provide improved means for synchronising and adjusting the deliveryof the solution automatically with the supply needs, that is to say, the delivery of solution is dependent upon the pressure in the water supply mains, or other fiow of the water.

Other objects will be apparent from the ensuing description.

Referring to the drawings which form a part of this specification:

Figure 1 is an elevation of a chlorinating apparatus, the control portion of the apparatus being in section.

Figure 2 is a part elevation on a reduced scale, looking in a direction at right angles to Figure 1.

Figures 3 and 4 are diagrams showing typical installations whereby the chlorinating solution is added to a water supply.

A cabinet 10 of wood or any other suitable material is provided with a hinged or other lid I I and a suitable fastener for said lid (not seen in the drawings) Within the cabinet is arranged an open-topped tank or container l2 which acts as an equalising vessel or balancing tank. An arm [3 is hinged to the cabinet I!) at M and extends across the top of the tank l2. A float device which is shown as an enclosed airtight box l5, but might be a ball or simply a bell open at the bottom, is carried by a depending bracket 13a from the arm l3 and depends into the tank l2. The arm 13 is also provided with a socket or cup l6 having a soft rubber or other suitable seating I! at the bottom and a number of orifices I8 in its side walls. The lid of the cabinet supports the solution flow tube I 9 by means of a sleeve or the like I90, which has a grip fitting or the like l9d to prevent vertical movement once the 2 adjustment is set, the tube [9 being connected by flexible tubing or any other suitable connection with the outlet cock 2| or the like of the main vessel 22 containing the solution. The vessel 22 may be one of a battery of vessels and may be of large capacity. The flow tube l9 extends downwards through the lid of the cabinet and its lower end l9a dips into the socket IS on the hinged arm l3, the said lower end 19a being sealed except for a small outlet orifice I91). It will be seen that normally the solution will fiow through this orifice l9b into the socket or cup I6 and through the orifices iii in the side walls of the socket I 6 into the tank l2. If, however,

the'level oi the solution in the tank rises above the required level the float l5 rises and presses the seating I! in the bottom of the socket l6 up .to the orifice l9b. in the bottom of the flow tube 19, so shutting off the flow until the level in the tank 12 has fallen again. A tube hereinafter called'the syphon drip tube 23 dips into the tank l2 and extends through the wall of the cabinet where it is supported by an external arm 24 adjustably secured by nuts 25 or other means 25 to a rod 58. The cabinet is provided with openings .34, and 35 to accommodate the hinge I4 and tube 23 respectively. A 'funnel 36 or the like is provided to receive the drips from the tube 23.

A pivoted lever 40 which is shown mounted on the top of the cabinet I0 on a bracket 4| but which could alternatively be mounted on one side or end of the cabinet, carries a weight 42 at its free end and is attached at the other end to a vertical rod 43 carrying a vessel 52 which is shown as a vertical tube. The tube 52 supports the threaded rod 58 which adjustably carries the arm 24 which supports the syphon drip tube 23. On either side of the vertical tube 52 is fitted a guide rod 53 sliding through an angleplate to correct any lateral movement. The vertical tube 52 is sealed at the bottom, but through said bottom an outlet tube 55 extends upwards for some distance, and preferably nearly to the top of the vertical tube 52. Depending into the vertical tube is a small-bore feed pipe 56 usually controlled by a stop cock, said feed pipe 56 being susceptible to mains pressure so that when pumping commences it receives water from the rising main, and discharges the water into the vertical tube, the added weight of which overbalances the weighted lever 40 and lowers the drip tube arm 24 as before. When the water in the main tube 52 rises to the top of the outlet lube 55, the surplus water flows out by way of drip tube 23 to the off position. The funnel 36 may be carried by a bracket 59.

In the installation as shown in Figure 3,. the solution from the funnel 36 is taken directly'down the well 6| alongside the suction pipe 62" which leads to the pump 63 and thence by way: of' a:

pipe 64 having a reflux valve 66 to a storage tank 65, the pipe 56 leading to the chlorinator having a control cock 68. In Figure 4 the solution from the funnel 36 drips into a suction seal tank 10 to obviate any air being drawn into the suction pipe 62; the tank 10 feeds the pipe 62 by way of a pipe M having a cock 12. Theconnection 56 leading from the rising main pipe 64 to the chlorinator has a branch l-3- leading by way of a cock H to thesuction' sea-l tank 10.

Having now described our invention, what we claim as new and desireto secure" by Letters Patent is:'
